carcass o t r Security- The trussing-frame provided with a suspension 55 as above described is particularly suitable for use in apparatus such as described in the specification of application No. 699,260 filed simultaneously herewith, wherein the cages have to meet obstructions, such as trap doors and chutes, when passing into and out of cooking and washing appliances, the guards 9, 9, which bulge beyond the wires 3, 3 then striking and sliding on these parts and protecting the carcass.

The locking pawl avoids accidental removal of the cage under these conditions, whereas it enables the operators quickly to attach and detach the cage to and from the conveyor, when required.

In order that the cage may be adjusted to receive carcasses of different sizes, the wires 3, 3 and the guards 9, 9 may be made telescopic, as indicated in Figures 5 and 6. In such a case, each locking-bar may be adapted to lock the cage after adjustment, for example, its lower end may have a series of holes 21 to receive a linch pin or cotter pin 22, as indicated in Figure '7. Locking bars of different length to suit these adjustments may be used.

The invention is not limited to a wire-work cage so long as it is provided with means for engaging with the carcass and the legs and wings to hold them in trussed position, as above described, and not in contact with any extensive surface likely to interfere with the cooking or treatment in oil.

I claim:

1. A truss-frame for retaining the carcass of a chicken or other bird in trussed condition during cooking, or other treatment preparatory to canning, comprising two main parts, one adapted to be inserted in the carcass to support the same from the inside and another adapted to support the carcass from the outside and having means for engaging with the legs and wings so as to hold them in the trussed condition, the part of the truss-frame which is inserted in the carcass having means for interlocking it with the other part of the truss-frame, when the carcass is in said frame.

2. A truss-frame for retaining the carcass of a chicken or other bird in trussed condition, comprising a wire cage for receiving the carcass of the bird and having means for engaging with the legs and wing bones of the carcass, and a locking bar adapted to be inserted in the carcass when in said cage and to interlock with said cage.

3. A truss-frame for retaining the carcass of a chicken or other bird in trussed condition, comprising a cage for receiving the carcass of the bird and having means for engaging with the legs and wing bones of the carcass, a locking bar adapted to be inserted in the carcass when in said cage and to interlock with said cage, and suspension means on said truss frame.

4. A truss-frame for retaining the carcass of a chicken or other bird in trussed condition during cooking, comprising a wire cage for receiving the carcass of the bird and having upper loops for engaging with the knuckle-bones of the legs and having lower loops to receive the wing bones and neck end of the carcass and means for locking the carcass in said cage.

5. A truss-frame for retaining the carcass of a chicken or other bird in trussed condition during cooking, comprising a wire cage for receiving the carcass of the bird and having upper loops for engaging with the knuckle-bones of the legs and having lower loops to receive the wing bones and neck end of the carcass and a locking bar for locking the carcass in said cage and comprising a tapered and pointed portion and loops for interlocking with the upper part of the cage.

6. A truss-frame for retaining the carcass of a chicken or other bird in trussed condition, comprising a wire cage having wires for supporting the back of the carcass, lower loops for the reception of the wing-bones and neck end of the carcass and upper loops for receiving the knuckle bones of the legs of the carcass, said back supporting wires being intermediate of said upper and lower loops and being telescopic, substantially as and for the purposes hereinbefore set forth.

'7. A truss-frame for retaining the carcass of a chicken or other bird, comprising a wire cage having upper and lower loops for the reception of the knuckle bones of the legs and for the winga bones and neck end of the carcass, respectively, wires for supporting the back of the carcass and other wires bulging beyond said back supporting wires to guard the carcass and a locking bar for securing the carcass in said cage.

8. A truss-frame for retaining the carcass of a fowl or other bird, comprising a cage and means for securing the carcass of the bird within the cage, said frame being adapted to be supported on a supporting stirrup, an element forming an extension of the cage and having an end formed for passage through said stirrup, and a pawl carried by said end, said pawl being freely movable through the stirrup and automatically assuming a position beyond the stirrup to prevent casual disconnection of the stirrup and cage.

9. A truss frame for retaining the carcass ofa chicken or other bird, including a cage to re ceive the carcass, an extension from the cage, the free end of the extension being formed to provide a hook, said frame being adapted to be supported on a conveyor stirrup designed to receive the hook and swingingly support the cage, and a gravity-operated latch carried by the hooked end of the extension, said latch being freely movable through the stirrup in one direction and automatically assuming a position beyond the stirrup to prevent casual return movement, whereby the cage is movably supported from the stirrup and prevented from casual disconnection therefrom.
